I have no clue. I was troubleshooting a route in Los Angeles yesterday and the route changed a couple of times over a period of about 10 minutes, but the road was turning red, indicating a traffic pileup.

Either that, or the map update has begun and that particular tile was updating while you were playing with it. But in that case, it wouldn't have switched back.

This intersection is even more complicated, but the type of layout does resolve most if not all of these issues. Take a REALLYCLOSE look at the junctions to see the detail.

That intersection is complicated, but some of the changes you've made seem to go against the #1 guideline for mapping. I see no purpose to this segment for example. It's just to give a left turn instruction?

The simple answer is yes...but those little segments also prevent crazy routing issues. Several URs popped up in that intersection with very bad routes through it. By losing the intersections, they simply can't happen.

I don't understand how this intersection would solve my routing problem. Both routes in my example (simply making the left turn or making a right turn / U-turn) are valid permitted routes. Its just that the right/U-turn makes no sense from a practical routing perspective. What waze is essentially doing is giving this route. I don't see that your intersection would prevent this.

I have to admit, when I looked at this Saturday night, it was routed correctly so I guess I misunderstood what was happening. I didn't re-check it before I posted my examples, and now that I see it, I don't think they'll help.

The only possible thing I noticed is that on the Live Map, the section of East West Blvd between the two sets of lanes of Gov Ritchie Hwy has an avg speed of 0 mph. I realize that info isn't necessarily what Waze uses, but it may have some merit. Perhaps deleting and rebuilding the 3 segments from before the intersection through the turn may help?

I just figured something had to be amiss with that junction so I pulled it apart (without saving it) and there it was.

That right turn w/ u-turn is actually the 3rd best route through that intersection. If you stay straight through to Pasadena Rd, there is a valid u-turn that could be made at Oak Ave. There has to be something that is keeping Waze from routing straight. The turns are also enabled with that segment too, but I have to imagine that little segment doesn't help matters.

Agreed...these little extra road segments are nearly impossible to find otherwise. They seem to wreak havoc wherever they appear. Maybe we should name them gremlins?
